Phoenix Is Heating Up This Week — Here’s How Hot It Gets

PHOENIX, AZ — If you're already reaching for the AC remote, you're right on cue.

Phoenix is heading into a stretch of sunny, dry weather this week, with temperatures nudging above normal before easing back by the weekend, a classic early-summer pattern for the Valley.

The National Weather Service is calling for mostly sunny skies through the week, with highs climbing steadily through midweek and peaking around 5 degrees above normal by Wednesday.

That's not a record-breaker, but it's enough to feel it. The saving grace is overnight lows: thanks to the dry air mass sitting over the region, nights should stay fairly comfortable, and forecasters are only flagging patchy areas of moderate HeatRisk.

Stay hydrated and limit midday time outdoors, but this isn't an extreme heat event, forecasters said.

Metro Phoenix stays dry all week. The only exception plays out far to the east, where moisture drifting in from New Mexico could spark mountain thunderstorms in eastern Arizona by Wednesday.

The weather service noted it "would not be out of the question for a few thunderstorms and lightning strikes skirting far eastern Gila County Wednesday afternoon," with that chance lingering into Thursday in the mountains.

By late week, a shift in the broader pattern brings cooler westerly flow, and temperatures should return to near normal or even slightly below by the weekend. For Phoenix, that's a welcome reset.

On the aviation front, the weather service expects smooth conditions at Sky Harbor, Mesa Gateway, Scottsdale, and Deer Valley airports through the forecast period, with light and predictable winds.
